Benefits of technology

[0010] By means of the processing data generating system capable of generating a three-dimensional processing pattern by specifying two-dimensional subject pattern information and a three-dimensional profile of printing surface at the user's option, it is facilitated to obtain a three-dimensional processing pattern such as a cutting pattern for engraving a work with a subject pattern including thick cut lines or a cut surface greater in width than a minuscule laser beam spot by specifying a simplified two-dimensional processing pattern and a shift pitch at which the simplified two-dimensional processing pattern is continuously or intermittently shifted. Conventionally, although the use of a minuscule laser beam spot realizes processing of a sharp profile of pattern with high precision, it imposes difficulties in pattern design on users if intending to engrave a thick cut line or a cut surface greater in width than the minuscule l...

Embodiment Construction

[0069] In the specification, the term “processing” as used herein shall include mean and refer to printing or marking operation and cutting operation. The term “processing pattern” as used herein shall mean and refer to a printing or marking pattern and a cutting pattern. The term “subject pattern” as used herein shall include mean and refer to a pattern subject to printing or marking and cutting and is described as a subject pattern or a cut pattern.

[0070] Referring to the accompanying drawings in detail, and in particular, to FIG. 1 showing a laser processing system 100 in accordance with an embodiment of the present invention, the laser processing system 100 comprises a laser output unit 1, a laser control with 2 and an input unit 3. Contrast to typical laser processing systems for processing a work by scanning the work with a two-dimensional pattern by a laser beam, the laser processing system 100 has a three-dimensional scanning unit for scanning a work in three dimensions by ...

Abstract

Laser processing data based on which a laser processing system scans a work with a laser beam adjustable in focal distance in two dimensions is generate by specifying a two-dimensional pattern in an X-Y coordinate plane and a shift pitch at which the two-dimensional pattern is shifted in a Z-axis direction and repeatedly shifting the two-dimensional pattern at the shift pitch in the Z-axis direction in synchronism with the scan with the two-dimensional pattern.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a method of and system for generating laser processing data representing a processing pattern based on which a laser processing system processes a subject surface by varying a focal distance of a laser beam during a scan of a subject surface in two dimensions by the laser beam, a computer program for implementing the method of generating the laser processing data, and a laser marking system including the system for generating the laser processing data. [0003] 2. Description of Related Art [0004] Laser processing systems are used to process a given surface of a work (work surface) by scanning the work surface in two dimensions with a laser beam generated by a laser oscillator. The laser beam focused on the work surface is moved in X and Y directions in a surface perpendicular to an optical axis of an X-Y scanner. Such a laser processing system is widely used as a laser marking system ...
